Use recommended version of $(document).ready

[hirasso]

Hi there! First of all, thank you so much for this very handy plugin! ❤️

Today I noticed that the initialization in scripts_admin.js didn't fire on one of my sites:

jQuery(document).on('ready', function() {...})

Changing it to the recommended way fixed the plugin for me:

jQuery(document).ready(function() {...})

I don't have the issue on all of my sites using your plugin, but I still think it's worth it to use the official jQuery-way for initializing the script.

@pwkip any chance this would be merged? Otherwise I'll close it :)

Still need to review this, but currently not much time. You can leave it open. And thanks!
